| Abstract | ||
| ABSTRACT : An experiment was conducted to evaluated the effect of injecting hatching eggs with different concentrations of vitamin A at same body dimension and its lengths of broiler chickens . Six hundred eggs hatching(Hubbard) were divided into five groups(150 eggs for each group) . Treatment groups were distributed as follows :- T1 control group(without injection) ,T2,T3andT4 injected by 100,150 and 200 I.U vitamin A/ egg respectively at age of zero . Post hatching were studied same body dimension and its lengths of broiler chickens at age 35 days . The data obtained revealed the following :- There were consequential differences in body length , circumambient of breast , body fleshing and breas and drumstic bones length , also significant (P <0.05) differences and increase in circumambient of thight , length of keel and thight for injected treatments T3 , T4 comparision with control T1 . It could be concluded from this study that injecting hatching eggs with different levels of vitamin A improved carcass traits and body dimensions in broilers . | ||
